The gunmen ordered everyone on the floor, and fired a shot into the ceiling. Workers and customers were locked inside the building for the approximately 30-minute ordeal. The gunmen took money, car keys and cellphones from the victims.

No one was injured, despite the violent nature of the crime and the half-hour duration of the holdup.

Authorities have not released a specific description of the gunmen. Anyone with information is asked to call the Orange County Sheriff's Office, or Crimeline at 1-800-423-TIPS. Callers are anonymous, and a tip leading to an arrest can bring a cash reward.
